Common Problems and Solutions of Industrial Diesel Power Generation 1

There are many reasons for the failure of industrial diesel generators. People can expect and must be prepared for unavoidable things in the industrial environment.

The following are the most common maintenance issues and possible solutions for industrial diesel generators.

Cooling liquid level drop alarm/stop

External or internal leakage is the main cause of low coolant level. Although many industrial diesel generators are equipped with this type of alarm device, there are few specialized alarm devices to prevent insufficient coolant. Generally speaking, this alarm is related to shutdown due to high coolant temperature. When the generator is equipped with a "near cooling medium temperature alarm" or "cooling medium temperature warning", you can determine the fault that caused the shutdown.

Cylinder heater

The cylinder heater actually heats the coolant circulating around the engine block. Maintaining cylinder temperature can prevent oil from becoming too rich at low temperatures.

A common misconception is that engines do not require heating in warm climates. The cylinder heater not only helps the engine start in cold weather. Due to the different metals used to manufacture engines, accelerated wear may occur during startup. Generally, pistons made of aluminum expand faster than iron cylinder liners. The rapid expansion of these pistons can cause wear on the piston skirts.

The cylinder heater reduces these wear by maintaining the temperature of the cooling system and expanding the cylinder liner.

Cooling liquid temperature alarm

The refrigerant low temperature alarm is mainly caused by a malfunction in the heating module. Use these heaters 24 hours a day, 7 days a week, and they often malfunction. However, the overall heater will never stop the engine from running. The extreme temperature inside the heating furnace is the cause of coolant circulation in the system. Sometimes you can hear the sound of coolant boiling in the cylinder heater.

Oil leakage - oil, fuel, or coolant

Daily maintenance can be carried out to prevent leaks. In most cases, oil spills are not real leaks, but rather the result of "wet accumulation". Accumulation of carbon particles, unburned fuel, lubricants, condensate, and acid in the exhaust system.

The most common coolant leakage is inside the cylinder heater tube. The extreme temperature generated by the large heater can accelerate the fatigue of the heater hose.

The most common malfunction in fuel leak repair is due to excessive fuel in the tank. This situation is generally caused by human factors or pump system failures. To avoid such situations, it is recommended that you hire a professional to refuel your industrial diesel generator.
